Conditional operator in Java

Question

Executing the following program is producing the following result, please explain the reason why the value of sum is 120 and of price is 100.

double sum=10, price =100;
sum+=price>=100?price * 1.1 : price;
Syso(sum);
Syso(price);

The output is 120 100

(1) This reads like a homework question. (2) Syso doesn't exist. (3) Please show your own progress first. — Konrad Höffner, Oct 10 '17 at 12:00
condition is price either equal to or greater than 100 then multiply price by 1.1.here condition is true so sum=10(old sum)+110(price after multiply) so result is sum=120 but multiply price is not assign to price so it not change and show price=100 — Mostch Romi, Oct 10 '17 at 12:07

expression ? value 1 : value 2

if expression is true, result is value 1 (first condition)

if expression is false ,result is value 2（second condition）

Example:

x = 1, x > 10 ? x : 10

expression: x > 10 => false

value 1: x value 2: 10

result is 10
